General Motors has revealed the next-generation V8 powerplant that will propel the upcoming 2014 Chevrolet Corvette, guaranteeing more horsepower, more torque and significantly better fuel economy.

The 6.2-litre LT1 V8 represents the most significant redesign in the small block’s nearly 60-year history with the addition of several technologies bringing the engine into the 21st century.

Chevrolet Corvette LT1 Engine - 3

Featuring direct injection, active fuel management cylinder shut down technology – a first for the Chevrolet Corvette – and continuously variable valve timing, GM expects the small block gen 5 LT1 engine to deliver 335kW and 610 Nm in the quickest, most powerful, standard Corvette ever, with an estimated 0-100km/h time of less than four seconds, all while being the most fuel-efficient version of the classic car ever.

The new technologies join an all-new advanced combustion system that incorporates a new cylinder-head design and a new, sculpted piston design.

Corvette chief engineer Tadge Juechter said the “Holy Grail” in the development of a performance car is to deliver greater performance and more power with greater fuel economy.

“And that’s what we’ve achieved.”

“By leveraging technology, we are able to get more out of every drop of gasoline and because of that we expect the new Corvette will be the most fuel-efficient 450 horsepower (335kW) car on the market.”

Chevrolet Corvette - Old and New

Though it’s too early for confirmation, a long-standing tradition – starting in 1997 with the 5.7-litre GenIII V8 – exists among the General Motors family of the Corvette V8 powerplant finding its way into the engine bay of Australia’s Holden Commodore, the newest of which is the Holden VF Commodore, due to go on sale in Australia in the first half of 2013.

    LOL finally they caught up to the Fords Coyote, now Ford just needs to do an update and they will be in front again.

    • Devil666

      Well, they are equalling the output of Ford’s engine with old designs mixed with modern innovations. This is also a far simpler mechanical design, more lightweight and compact, with a much better centre of gravity – keeping the weight low in the engine design. It’s also naturally aspirated for more immediate engine response.

      Probably hasn’t cost them much money to keep up with Ford – this engine is likely running a conservative state of tune, and speaking of tuning – I’m sure Hennessey will have this thing over 1,000HP very soon.

      • $29896495

        Actually I think you would find that direct driven valves are a simpler and more efficient design than push rods. At this point I would say they are squeezing the very breath out of that primitive tech by bolting on modern bits. But think how good it could be if they brought themselves into the 21st century.

        • DoubleBlue

           110% spot on “Huwtm”. You could learn a lot from this guy “Devil666″ that way you wouldn’t ended up embarrassing yourself  with the B.S comments above.!

      • old-and-burn`t-out

        not really, they only get the higher out put with a greater swept volume, it will be interesting to see if the new DI engine is reliable in the long run,  quite a few different brands have had trouble with valves carboning up,  including some of the up market brands, time will tell though.

    • Craig Simpson

      You are joking aren’t you. the coyote has only just surpassed the gen iv for performance (and only by about 10kw). Ford has been trying to catch upto gm/holden since 1997 and with this engine the performance crown will again be put beyond fords reach for quite some time to come. Most likely till beyond the falcons demise.

      • Schah7

         I don’t really think so eh   Bart whoops Craig Simpson

      • Zaccy16

        The falcons/FPV’s 5.0l supercharged v8 has a much better mid range than this naturally aspirated and the current v8 in the hsvs, also this engine could be tuned to  deliver way more than 335 kw

      • Andrew M

        Ford has had the I6T for nearly 10 years now which has had it over any V8 on the Australian market from GM or Ford.

        Also the era of around before 1997 was filled with V8′s simply built for noise with no massive performance advantage compared to how they are tuned today.

        Even todays 6cyls have more power than the V8′s of that era

        Sure Holden brought out the Gen111 motor which is what I assume you made reference to with post 1997, but the first additions had big problems with drinking oil and slapping pistons. They were far from reliable

        The new Coyote motor may only have 10kw on the GM motor, but its power is much more usable. Also, it doesnt even run an intercooler showing how under tuned it is

  • Robin_Graves

    Still got pushrods and 2 valves per cylinder?  Hardly 21st century, just got some injectors screwed into the combustion chamber (plenty of room with only 2 valves) and some phasers on the cam.  The claims about lower centre of gravity, we are talking a few kilos at most, against all the limitations of pushrods and 2 valves, clutching at straws for positives.

    • Pro346

      Most high powered drag engines still use 2 valves a cylinder and push rods…..the most powerful piston engined street cars in the world also use them, seen any 1500 HP boss or coyote v8s lately?

      • Acfsambo7

        Drag engines use pushrods because they are a more simple design and there are less moving parts. GM seem to be able to get their V8′s to work with pushrods quite nicely, though I think their Halo car should have the best tech engine wise they can.

        • Schah7

           I agree……..”their Halo car [Corvette] should have the best tech engine wise they can” BUT with this engine it sadly DOESN’T.

        • Zaccy16

          yeah your right, with new tech in these engines eg, replace push rods and the power increases will be substantial   

      • Robin_Graves

        Drag racers use the LSX engines because they are simple, easy to work on and you can replace them with a crate engine cheaply.  Drag engines also use massive cams which then require a high-stall converter to ‘get them out of the hole’ that massive cam engines have at low revs.  Hardly the stuff a production car can get away with.  Also the 1500HP engines are force fed.  Plenty of 2JZ’s getting those numbers from 3.0lt

        • Pro346

          Any engine can be made to make big HP…lsx engines are good because they have huge aftermarket support and are a good base for big HP.

    • Horsie

      Mate. do you think anyone cares how many valves per cylinder this engine has.
      The fact is, this engine will blow the doors off just about anything on the road including your LOL golf.

      • Horsie

        actually i think it could do that running on 3 cylinders.

      • Cbf

         Why care about fuel consumption, emissions etc?

      • Robin_Graves

        For a start I dont drive a golf.  A typical knuckle dragging Holden fan wouldn’t care how many valves its got purely the fact it has a bow tie on the front (even if it’s a VS V6) and it does a sick skid.  If you had half a brain you might understand something called BMEP and how Chev aren’t even in the ballpark of any engine in the last 20 years with this boat anchor.  Cheap, nasty and crude, kinda sums up GM and its fans in one sentence.

        • Golfmother

          SEEKEM  rex go get em boy you tell em , your right .

        • twincharger

          Robin im sure ive seen you driving around in a Golf,,,lol

          • Golfmother

            BARRY AND ROBIN  you should form a band , two piece on a flat top ,” staying alive” in a falcoon .

      • $29896495

        The BMW M135i will accelerate from 0-100km/h in just 4.9 seconds – puts this V8 into perspective don’t you think? 

        • Drac

          How so? This will be approx 3.9 seconds…

          • $29896495

            economy performance versatility. On par with current V8s, not a fantasy number. How’s that.

          • Drac

            Costs a lot more than current V8s, sounds worse and is a small car. No one in the market for a V8 would look twice at one.

          • $29896495

            VERY SMALL market these days. Getting smaller.

          • Drac

            Ok, go buy a corolla then

          • $29896495

            You may want a Corolla, nut I’d rather some thing along the lines of an OPC Astra GTC, if it’s all the same to you. (Unless of course Ford turn the EVOS into a real car) Then there’s the Civic Coupe the US gets, that would be cool 2.4 Lt 8000 RPM of screaming fun. They look good go well handle well and are reasonable at the pump too. Gotta learn and grow otherwise you stagnate and become a dinosaur. Not unlike oversize V8 sedans.  

          • Dave S

            A dubious claim. 3.9 in a 1 series, I dont think that ugly hatch is going that fast.

          • $29896495

            I think he was referring to the V8. My point was, do you need over 6 Lt of motor when a smaller one will do almost the same thing – if not better it in the real world. The BMW was just an example I plucked quickly from this site, but there are a lot of other cars that look and go better for less. 

    • Aaus

      Yeah but look at the Lexus ISF and the 5L engine on that is very high tech

      But it lacks a soul. It sounds nice and the power is smoother than silk. but doesn’t feel like American muscle V8

      • JooberJCW

        Because its not trying to be.

      • Holdens 4eva

        they still run the GM Ozzy built 5litre in supercars, pity they gave it away for the bowtie motors, economy was its weakest point but it had a distinct sound you could hear a mile away. Big ups to Ford Oz with the supercharged 6s and 8s and giving the Ozzy battler a car that performs well and aint cost an arm and a leg  ;)

    • Schah7

       Robin_G the old “Briggs&Strattion” er “Chev” boys probably feel the sun wouldn’t shine anymore if GM stopped making those,when ELVIS started out[1950's] V8 engines.

    • Roadtard

      GM did DOHC in the ZR1 Corvette about 20 years ago.  For whatever reason they’ve gone back (forward?) to OHV.  Get over it.

      Next Vette needs to deliver on quality,especially inside…

      • Robin_Graves

        I’m well and truly over it, so are the rest of the automotive world, like 30 years ago! I seriously dont understand why the waste so much energy trying to make a compromise work.  Its like the leaning tower of pisa, stack too much stuff on a poor foundation its only a matter of time before it falls over (emissions or fuel economy standards)

        • $29896495

          Or both

    • Car Fanatic

      This is possibly the only time I’ve ever agreed with Robin, seriously updated the engine, GM are stuck in a cubic inch time warp and keep pumping out the same old steam engine because it’s cheaper to do so, than to bring out advanced V8′s like Europe and Japan.

    • Kiwi 1

      Well said Robin. Also they can’t have ‘real’ independent variable valve timing with only one cam, so the results from this addition will be no where near as good as variable valve timing from separate inlet and exhaust cams. Another big boat anchor from GM where the theory of ‘lets make it bigger’ over-rides any spend on new technology.

      • DoubleBlue

         Spot on “Kiwi1″ you’re on-to-it more than these ignorant/time warped inefficient  GM Aussies.!

    • Dennis

      Do some research before commenting….

      The engine is 99.9% New…

  • Monk

    Less than 4secs from this one? Really?
    Maybe the later supercharged version…

    • Pro346

      Yes really…

    • F1orce

      Buddy it’s a 6.2L engine.

      Sub 4 seconds shouldn’t be a problem.

      And max speed of over 300km/h will be a breeze.

      • Monk

        Just seemed A LOT quicker than say the 6.2L GTS (325kW/550Nm) which from memory is 4.9s 0-100.  Dropping a second off that takes a lot of effort.

        • Phil

          GTS is listed at 1924Kgs. Current model base Corvette is listed at 1455kgs

        • Lindsay

          Takes a lot of effort?  The Corvette weighs 400kg less than the GTS!

          • Zaccy16

            and the corvette puts its power down better than the gts

        • $29896495

          You gotta remember that the Corvette is made out of Plywood and fibre glass. I’m saying it won’t weight or shouldn’t way anything like a two ton Commodore, where’s the performance?

  • F1orce

    Naturally Aspirated V8 FTW!

  • Wile E Coyote

    Nice try but size and weight for output still trails performance Euros.

    • Aussie and proud

      yeah and you pay how much more for performance Euro’s?

      • Lindsay

        Less than you’d pay for a Corvette in Australia, amusingly.

        • Craig Simpson

          Only because a private company has to do the conversion. If GM made a RHD version standard I’m sure it would be a lot cheaper.

          • Lindsay

            It most probably would, but that’s neither here nor there because the car doesn’t exist.

      • JooberJCW

        Yep, and how many euro N/A v8′s can do 0-100 in its given production chassis under 4 seconds.

        • Schah7

           Its only GM stating under 4 seconds……hasn’t been tested or proven yet.

        • $29896495

          what about some of the new Jags?

      • Schah7

         Ol’ “Aussie and IGNORANT” Hu.! lol

    • Lindsay

      You pays your money and you takes your chances.

      Let us compare a BMW M3 to the C6 Corvette.  Similar power output, torque goes to the Corvette because its engine is 50% larger.  The two engines are almost the same weight too.  Combined cycle fuel economy is very slightly better in the Corvette(!)

      Two different ways of achieving the same goal.

      • Wile E Coyote

        Yeah like radial tyres compared to cross plys. 
        Also I doubt the engines weigh almost the same.

        • Lindsay

          The best information I could find is that the M3′s engine assembly weighs 202kg and the Corvette’s weighs 450lb.  That’s as near as makes no difference.

      • $29896495

        How do you know the Corvette has better economy? Infact how do you get the weight figures?

        • Lindsay

          The US Department of Energy

          Search for “fuel economy”, it’s the number 1 result on Google.

    • Craig Simpson

      The merc v8 which is one of the engines you are no doubt referring to does produce more power (391kw in most modern iterations). But this 335kw figure that GM is putting out there now is most likely not it’s final state of tune for performance models and what it could eventually be upgraded to. So yes it might not be quite as efficient as the merc v8. It is however most likely a lot simpler, lighter and cheaper for use in other vehicles that gm sells around the world aside from the corvette. This 335kw engine is most likely what will find it’s way into the bog standard SS commodore for about $50k. While I have great respect for performance German and Jaquar cars. They are beyond the means for average Joe Australian struggling to pay electricity bills, fuel bills, telephone bills, water bills and a mortgage. Also have you heard the saying that the simple things in life are often the best.

    • Schah7

       The Euro guys find the Corvettes engine a great source of humour, entertainment & laughter @ boardroom meetings.

      • Mr Irony

        Corvette ZR1 produces 476 KW. Jeremy Clarkson took one to 284 kph on the Bonneville salt flats, which is a record for a production car.

        Have you bothered to check the facts?

        • DoubleBlue

           Most if not all Euro sports cars [don't need a salt lake]  do far better than your 284k on the open road.!

      • Lindsay

        *rolleyes*

        • DoubleBlue

           LOL Yeah the Euro Guys are probably laughing too hard to notice.

  • Sumpguard

    Why throw out what works? They may be pushrod but they are strong engines.

    • JooberJCW

      Exactly, a typical yank/Aussie muscle car buyer doesnt care about the latest innovation in they engines, as long its simple, sounds good and goes good is all it matters, GM don’t have spend uneccessary R&D money to not gain any better market share.

      • $29896495

        and they can brag about how big the thing is down the pub

    • Schah7

       Strong & nothing much else.

    • http://www.bryanbyrtrenault.com.au/ Modern Man

      Yeah, why make way for progress.

      give me my commodore 64 and Mac Classic back.

      Them were the days.

      I dont think caradvice would exist in its current format though.

  • Slick-slim87

    I thought this motor was suppose to be 5.5L not 6.2

    • Craig Simpson

       they changed it to 6.2 because it give more flexibility to the AFM.

    • Schah7

       You’re 100% right Slick-slim87 about the new 5.5 L v8 BUT GM soon realized that if they went to the smaller size engine it would not have been competitive. So[like usual] they GM had to use the 6.2 to be on par with the competitions smaller engines.

    • Shak

      Remember Gen V will be a family of engines, like Gen IV had displacements from 6.0 up to 7.0 litres. This new 6.2 litre engine is just the first Gen V engine to be revealed, and will most likley only see service in the basic Corvette variants, along with Holden’s V8 lineup. The high end peformance models will likely get engine variants which are probably still 1-2 years away from being revealed.

      • $29896495

        are we forgetting the Holden V8 line up is in the toilet? (sales wise) All this in reference to the Commodore seems like a moot point.

        • Shak

          Im sorry i dont follow. Whats your point? Yes Holdens V8 sales are declining, but this engine will still be making its way into a Commodore.

          • Lindsay

            “this engine will still be making its way into a Commodore”

            Just one?  You might not be far off!
